Abstract

This switch is pref. used in automobiles for the illumination of reversing lights and is operated by the gear box. The membrane (17) prevents contamination of the contacts (21, 23) by the oil of the gear box and the spring (26) takes up a long free travel. The spring (22), butting against the moving contact (23) and holding it in the open position, is weaker than the spring of the operating mechanism which can override it when brought into operation. A third spring (27) returns the plunger into its original position.
